I can can see the next batch of dated names coming back in. Dorothy, Ivy, Wilfred and Albert will get tired sounding and be replaced by Barbara, Patricia, Donald (or maybe not!) and Walter.
I can see more unisex, word inspired nature names, such as Ocean, Sage, Harbour, Forest, Storm, etc. Animal names too: Bear, Fox, Wren. Flower/plant names will continue to rise, but new parents will look for less usual flowers: instead of Rose, Poppy and Daisy, names like Marigold, Magnolia, Maple, Blossom, Primrose, Acacia will join the mainstream.
Popular names now (for boys and girls, but particular girls) tend to very soft sounding, vowel-heavy, liquid names: Eliana, Aurora, Arya, Olivia Lilia, Willow, Amelia. This means that even though Eliana for example, is outside the top 200, and there might be no other Eliana’s in her class, it doesn’t sound distinct from the mainstream. I can see a move away from this, towards harder sounding names as parents want something more sonically distinct. Margot is leading the way on this with a hard G sound, while still having the trendy O sound at the end.I think more names with hard B, D, C/K and G sounds will rise int he future.
Names will continue to diversify. The percentage of babies called the top name has decreased massively over the years as parents look for more different names for their children. Babies with names in the top 100 will decrease further and further in number.
